ABSTRACT

Systems and methods for preventing machine learning models from negatively affecting mobile devices are provided. For example, a mobile device including a camera, memory devices, and one or more processors are provided. In some embodiments, the processors may be configured to provide images captured by the camera to a machine learning model at a first rate. The processors may also be configured to determine whether one or more of the images includes an object. If one or more of the images includes the object, the processors may be further configured to adjust the first rate of providing the images to the machine learning model to a second rate, and in some embodiments, determine whether to adjust the second rate of providing the images to the machine learning model to a third rate based on output received from the machine learning model.

TECHNICAL FIELD

The disclosed embodiments generally relate to machine learning and resource management on mobile devices. Some embodiments are drawn to preventing machine learning models from negatively affecting mobile devices through intermittent throttling.

BACKGROUND

Machine learning models made using artificial intelligence provide computing systems the ability to learn and improve with experience without additional programming. To advance technology, software developers have increased using machine learning models to provide more advanced or intelligent computing systems to their end users. Software developers design most machine learning models for execution by high-powered computing systems, such as desktop computers, with a sustained energy source (e.g., an electrical outlet) because the machine learning models may include complex algorithms and/or models that require substantial processing speed and/or memory.

End users have, however, increased their use of mobile devices that run mobile applications that impact their daily lives. In response, software developers have created mobile machine learning model frameworks to execute (e.g., run) machine learning models, including those frameworks designed to execute on desktop computers and on mobile devices. However, mobile devices are often not high-powered and have limited access to energy sources (e.g., a battery). Thus, the machine learning algorithms often negatively affect mobile devices before the machine learning models can complete their execution, that is, machine learning algorithms may cause mobile devices to overheat, overload the mobile device's memory or processors, or drain the mobile device's batteries.

Thus, there is a clear motivation to prevent machine learning models from negatively affecting mobile devices during operation. In view of these and other shortcomings and problems with machine learning models on mobile devices, improved systems and techniques are desirable.

SUMMARY

The disclosed embodiments address disadvantages of existing systems by providing novel systems, methods, and techniques for preventing machine learning models from negatively affecting mobile devices through intermittent throttling. The disclosed systems and methods may prevent the negative effects caused by legacy and/or current machine learning models that were designed to execute on desktop computers. The disclosed embodiments are unlike any prior implementations and provide multiple ways, as described below, to prevent machine learning models from negatively affecting mobile devices.

Certain disclosed embodiments provide a set of systems, devices, and methods. For example, a mobile device comprising a camera, one or more memory devices storing instructions, and one or more processors configured to execute instructions may be provided. The one or more processors may be configured to execute instructions to provide images captured by the camera to a machine learning model at a first rate. The one or more processors may also be configured to execute instructions to determine whether one or more of the images include an object. If one or more of the images includes the object, the one or more processors may be configured to execute instructions to adjust the first rate of providing the images to the machine learning model to a second rate and determine whether to adjust the second rate of providing the images to the machine learning model to a third rate based on output received from the machine learning model.

Moreover, certain disclosed embodiments provide another set of systems, devices, and methods. For example, a mobile device comprising an input device for capturing inputs, one or more memory devices storing instructions, and one or more processors configured to execute instructions may be provided. The one or more processors may be configured to execute instructions to provide the inputs to a machine learning model at a first rate. The one or more processors may also be configured to execute instructions to determine whether one or more of the inputs includes an object. If one or more of the inputs includes the object, the one or more processors may be further configured to execute instructions to adjust the first rate of providing the inputs to the machine learning model to a second rate and determine whether to adjust the second rate of providing the inputs to the machine learning model to a third rate based on output received from the machine learning model.

Certain disclosed embodiments provide yet another set of systems, devices, and methods. For example, a system comprising one or more memory devices storing instructions and one or more processors configured to execute instructions may be provided. The one or more processors may be configured to execute instructions to capture a plurality of inputs. The one or more processors may also be configured to execute instructions to provide the inputs to a machine learning model at a first rate. In addition, the one or more processors may be configured to execute instructions to determine whether one or more of the inputs includes an object. If one or more of the inputs includes the object, the one or more processors may be further configured to execute instructions to adjust the first rate of providing the inputs to the machine learning model to a second rate and determine whether to adjust the second rate of providing the inputs to the machine learning model to a third rate based on output received from the machine learning model.

Further, certain disclosed embodiments provide a set of systems, devices, and methods. For example, a mobile device comprising a camera for capturing images, an accelerometer for capturing gravitational force measurements, one or more memory devices storing instructions, and one or more processors configured to execute instructions. The one or more processors may be configured to execute instructions to determine whether the mobile device is still based on gravitational force measurements captured by the accelerometer. The one or more processors may also be configured to execute instructions to provide an image captured by the camera to a machine learning model if the mobile device is still.

Certain disclosed embodiments provide another set of systems, devices, and methods. For example, a mobile device comprising an input device for capturing inputs, a sensor, the sensor capturing movement characteristic measurements, one or more memory devices storing instructions, and one or more processors configured to execute instructions. The one or more processors may be configured to execute instructions to determine whether the mobile device is still based on a movement characteristic measurement captured by the sensor. The one or more processors may also be configured to execute instructions to provide an input to a machine learning model if the mobile device is still.

Certain disclosed embodiments provide yet another set of systems, devices, and methods. For example, a system may comprise one or more memory devices storing instructions and one or more processors configured to execute instructions. The one or more processors may be configured to execute instructions to receive, via a camera of a mobile device, a plurality of images. The one or more processors may also be configured to execute instructions to receive, via an accelerometer of a mobile device, a plurality of gravitational force measurements. The one or more processors may further be configured to execute instructions to determine whether the mobile device is still based on at least one gravitational force measurement. In addition, the one or more processors may be configured to execute instructions to provide an input to a machine learning model if the mobile device is still.

FIG. 3 is a flowchart of an exemplary process 300 preventing machine learning models from negatively affected mobile devices through intermittent throttling. Mobile device 110 may use one or more applications including machine learning model applications 272, sensor application 274, and/or other applications (not depicted) to complete the steps of process 300. Process 300 may prevent, for example, overheating and battery drain of mobile device 110 while the mobile device 110 processes inputs (e.g., images, text, etc.) from input devices 220 (e.g., cameras, keyboards, etc.) using a machine learning model application 272.

At step 310, mobile device 110 may capture one or more inputs via one or more input devices 220. For example, in some embodiments, mobile device 110 may capture images via a camera (e.g., an input device 220). Mobile device 110 may, additionally or alternatively, also capture text, sounds, etc. via input devices 220, such as keyboards, recording device, etc. Mobile device 110 may capture the inputs at a rate, such as frames per second.

At step 320, mobile device 110 may provide one or more of the captured inputs into a machine learning model via machine learning model application 272. Mobile device 110 may provide one or more of the captured inputs into a machine learning model, via machine learning model application 272, by providing the captured inputs to processor 240 for use in the machine learning model.

In some embodiments, mobile device 110 may provide a first input of the inputs to the machine learning model while capturing a second input of the inputs at step 310. In certain embodiments, mobile device 110 may capture a set of the inputs at step 310 before providing the inputs to the machine learning model via machine learning model application 272. Mobile device 110 may provide one or more of the captured inputs into the machine learning model at a certain rate.

After providing one or more inputs to the machine learning model, at step 330, mobile device 110 may determine whether at least one of the captured images includes an object. In some embodiments, step 330 may occur before mobile device 110 begins providing one or more of the captured inputs into a machine learning model (in step 320). In other embodiments, step 330 may occur after or during step 320.

To determine whether an image includes an object, mobile device 110 may determine whether the image includes an object based on the output from the machine learning model or using some other technique. For example, mobile device 110 may determine that the image includes an object based on determining that the object is depicted in the scene. To be depicted in the scene, mobile device 110 may determine that the whole or a part of the object is depicted in the scene. For example, mobile device 110 and/or machine learning model application 272 may retrieve the general outline for an object from database 140 and/or server 150. Mobile device 110 and/or the machine learning model may then determine whether a part or the entire outline for the object is depicted in the image by comparing one or more outlines in the image to determine that the object is depicted in the image.

Using the general outline of the image as a comparison technique to see if the object is depicted in the image is only exemplary. In some embodiments, mobile device 110 and/or machine learning model application 272 may determine that the image includes an object based on retrieving one or more colors, shapes, dimensions, shadows, or other properties of the object or the image of the object in addition or alternative to using the general outline of the image. In certain embodiments, mobile device 110 and/or machine learning model application 272 may determine that the image includes an object based on determining that an object is depicted in the center of the image.

Machine learning model application 272 may also use historical images and/or determinations of objects to determine whether the object is depicted in the image. The machine learning model application 272 may be trained to determine whether the object is depicted in the image using supervisory, semi-supervisory, or non-supervisory techniques. The mobile device 110 and/or machine learning model application 272 may also determine or be configured to detect certain objects. For example, mobile device 110 and/or machine learning model application 272 may determine or be configured to detect, e.g., cars rather than houses, money rather than food, etc.

If mobile device 110 does not determine that the image includes an object, mobile device 110 may continue one or more of the previous steps, such as capturing images (step 310), providing inputs into the machine learning model (step 320), and/or determining whether the inputs include an object (step 330). In some embodiments, mobile device 110 may stop processing the image and/or use other techniques, such as those discussed in relation to process 400 below.

If mobile device 110 does determine that the image includes an object, at step 340, mobile device 110 may adjust the rate of providing the inputs to the machine learning model. In some embodiments, mobile device 110 may adjust the rate of providing inputs to the machine learning model by increasing the rate. For example, mobile device 110 may adjust the rate of providing images at 50 images per second to 100 images per second. Mobile device 110 may increase the rate at this step because mobile device 110 may need to utilize more resources to identify the type of the object more efficiently. However, the reason why mobile device 110 may not have increased the rate before reaching this step because mobile device 110 may have inefficiently used its resources when there is no identifiable object, which potentially may cause the machine learning model application 272 to negatively affect mobile device 110 before a type of object is determined.

At step 350, mobile device 110 may adjust the rate based on one or more outputs received from the machine learning model. Output may include a confidence score and/or an object type. The confidence score may identify how confident the machine learning model is that the image includes an object that matches the object type. An output may, additionally or alternatively, correspond to an image, that is, the output may be generated by the machine learning algorithm as a result of mobile device 110 providing an image to the machine learning algorithm. Thus, as the machine learning model is more confident that an object in the image matches a certain object type, mobile device 110 may increase the rate of providing the inputs to the machine learning model to identify the type of the object more efficiently. However, as the machine learning model is more confident that an object in the image matches a certain object type, mobile device 110 may decrease the rate of providing the inputs to the machine learning model, for example, to preserve resources and prevent negative events. For example, mobile device 110 may increase the rate if mobile device 110 determines that the confidence score exceeds a confidence threshold value (e.g., 90%, 85%, 80%, etc., confidence) and/or decrease the rate if mobile device 110 determines that the confidence score is below a second confidence threshold value (e.g., 10%, 20%, 30%, etc., confidence) or does not exceed the confidence threshold value (e.g., 90%, 85%, 80%, etc., confidence).

In some embodiments, machine learning model application 272 may output some values that are inconsistent with other values. Thus, in certain embodiments, mobile device 110 may compare an aggregate confidence score of two or more confidence scores of the outputs to the confidence threshold value. Mobile device 110 may calculate the aggregated confidence score (e.g., weighted average confidence score) based on a weighted average of object types and confidence scores. For example, each confidence score may be weighted by a factor according to its identified object type. Mobile device 110 may increase the rate if mobile device 110 determines that the aggregated confidence score exceeds a confidence threshold value (e.g., 90%, 85%, 80%, etc., confidence) and/or decrease the rate if mobile device 110 determines that the aggregated confidence score is below a second confidence threshold value (e.g., 10%, 20%, 30%, etc., confidence) or does not exceed the confidence threshold value (e.g., 90%, 85%, 80%, etc., confidence).

Mobile device 110 may adjust the confidence threshold value via a sensor and/or sensor application 274. For example, mobile device 110 may increase the confidence threshold value (e.g., 90%, 85%, 80%, etc., confidence) if the available battery life of the mobile device is below a certain predetermined level. For instance, mobile device 110 may increase the confidence threshold value from 80% to 90% to preserve resources and by making it less likely for mobile device 110 to increase the rate in step 350. Mobile device 110 may decrease the confidence threshold value from 80% to 70% to increase the efficiency of mobile device 110 and the machine learning model by making it more likely for mobile device 110 to increase the rate in step 350. Other sensors and/or sensor applications, as described above, may also be used in real-time to adjust the confidence threshold value and, thus, balancing the efficiency of mobile device 110 to, for example, use machine learning model to identify the type of object in the captured images with the potentially negative effects of the machine learning models on mobile device 110. Mobile device 110 may increase or decrease the second confidence threshold value to obtain the same results.

FIG. 4 is a flowchart of an exemplary process 400 preventing machine learning models from negatively affecting mobile device 110 through intermittent throttling. Mobile device 110 may use one or more applications, including machine learning model applications 272, sensor application 274, and/or other applications (not depicted), to complete the steps of process 400. Process 400 may prevent, for example, overheating and battery drain of mobile device 110 while the mobile device 110 processes inputs (e.g., images, text, etc.) from input devices 220 (e.g., cameras, keyboards, etc.) using a machine learning model application 272.

At step 410, mobile device 110 may capture one or more inputs using techniques similar to those described above in relation to step 310. At step 420, mobile device 110 may capture one or more movement characteristic measurements. A movement characteristic measurement of mobile device 110 may include, for example, a measurement of gravitational force on mobile device 110, a speed of mobile device 110, an acceleration of mobile device 110, a rotational speed of mobile device 110, a rotational acceleration of mobile device 110, a displacement of mobile device 110, or the like. In some embodiments, mobile device 110 may capture, via one or more sensor applications 274 and/or sensors 230, one or more movement characteristic measurements. For example, mobile device 110 may use accelerometer (e.g., sensor) 230 to capture one or more gravitational measurements. Mobile device 110 may, additionally or alternatively, capture other characteristic measurements as described above in relation to FIG. 2.

At step 430, mobile device 110 may determine whether mobile device 110 is still based on one or more movement characteristic measurements. Alternatively, mobile device 110 may determine whether mobile device 110 is moving at a certain speed, rotating, etc. In some embodiments, mobile device 110 may determine that the mobile device is still if the movement characteristic measurement does not exceed a movement threshold value or determine that the mobile device is not still if the movement characteristic exceeds a movement threshold value. Thus, in some embodiments, mobile device 110 may determine whether mobile device 110 is still based on whether the movement characteristic measurement is nonexistent, that is, the movement characteristic may indicate that mobile device 110 has little to no movement.

In some embodiments, mobile device 110 may use an average movement characteristic measurement which may be compared to the movement threshold value in order to determine whether mobile device 110 is still. Mobile device 110 may determine that the mobile device is still if the movement characteristic measurement does not exceed the movement threshold value or determine that the mobile device is not still if the movement characteristic exceeds the movement threshold value.

Mobile device 110 may determine the movement threshold value based on the historical movement characteristic measurements captured by sensor 230 and/or sensor application 274. In some embodiments, mobile device 110 may base the movement threshold value on a movement characteristic range. The movement characteristic range may be based on the historical movement characteristic measurements. For example, mobile device 110 may determine, using historical movement characteristics for user 105 of mobile device 110 and/or other users of other mobile devices, a gravitational force range between 0.1 N to 0.5 N. Mobile device 110 may then determine the movement threshold value based on the range, such as the average of the range, the median of the range, the lower median of the range, etc.

Mobile device 110 may determine the movement threshold value based on the range to determine when the mobile device 110 is still for a particular user (e.g., user 105) and/or when the mobile device 110 is still for an average user or a range of users. Mobile device 110 may determine the average user or range of users based on users who use the same type of mobile device as mobile device 110, etc. The same type of mobile device 110 may include the mobile device of the same manufacturer, the same make, the same model, the same release date, the same mobile category (e.g., touchscreen phones, flip-phones, keyboard phones, etc.), the same size, the same processor speed, the same memory, any combination thereof, and/or the like.

As with the confidence threshold value discussed in 350, mobile device 110 may adjust the movement threshold value, discussed here, according to sensor 230 (e.g., battery life) and/or sensor application 274. For example, mobile device 110 increases the movement threshold value if the available battery life of mobile device 110 is below a certain level to make it harder for mobile device 110 to determine that it is still in order to prevent negative effects. Additionally or alternatively, mobile device 110 may decrease the movement threshold value if an available battery life is above a certain level to make it easier for mobile device 110 to determine that it is still to increase efficiency of mobile device 110 and/or machine learning model to determine, for example, the type of an object. In some embodiments, mobile device 110 may deactivate the input device if the available battery life is below a certain level to reduce strain on mobile device 110.

If mobile device 110 determines that mobile device 110 is still, mobile device 110 may provide the inputs to the machine learning model (step 440). In some embodiments, mobile device 110 may continue to check and/or determine whether mobile device 110 is still. In some embodiments, mobile device 110 may discontinue providing inputs to the machine learning model if mobile device 110 determines that the movement characteristic measurement exceeds a movement threshold value, that is, mobile device 110 may determine that mobile device 110 has moved or not become still enough to provide inputs to the machine learning model.

Mobile device 110 may combine one or more steps of FIG. 3 and FIG. 4 to prevent and/or reduce negative effects, for example, overheating, save battery life, etc. Mobile device 110, for example, may perform step 330 of FIG. 3 (determining whether the inputs include an object) before performing step 430 (determining whether the device is still) to complete process 400. Mobile device 110 may also include steps of process 400 to complete steps of process 300. In some embodiments, mobile device 110 may determine, while completing steps of process 300, to instead complete process 400, and/or vice versa. Additional and/or alternative steps may also be added to process 300 and/or process 400. Steps may also be deleted from process 300 and/or process 400.
